The latest release from ITEM Software is an extraordinary collection of new capabilities that provides a customizable, cross-platform, multi-user, open frame-work. With iQT, you are no longer limited by the technology choices of software vendors or chained to infrastructure requirements of their products. It provides component failure rates for a list of categories. It also contains the underlying conditions for which the component failure rates apply reference condition. Focused on reliability, safety, and risk assessment, our iQT product is a highly extensible framework that provides common infrastructure for any kind of system modeling.

SN Standard provides frequently updated failure rate data at reference conditions and stress models necessary for parts count and parts stress predictions. The reference conditions adopted are typical for the majority of applications of components in equipment. Under these circumstances the SN standard are used as a basis for conversion of the failure rate data at reference conditions to the actual operating conditions in the case that operating conditions differ significant from reference conditions.
To an increasing degree, customers require demonstration of reliability calculations for the products. The failure rate is the most frequently used characteristic in determining the reliability of subassemblies and units of equipment.
The component failure rates specified in the individual parts of the SN standard are used by Siemens AG and the Siemens companies as a uniform basis for reliability predictions. This standard also contains the underlying conditions for which the component failure rates apply reference conditions. Reference to such conditions is needed when failure rates are stated or when values from different sources are compared. The stress models described in this standard are used as a basis for conversion of the failure rate data at reference conditions to the actual operating conditions.

Siemens SN 29500
Dealing adequately with technical uncertainties. All 12 documents have individual revisions, which makes it difficult to name a formal SN revision. For electromechanical components like switches, relays, contactors and connectors, Siemens SN offers the most sophisticated and therefore the best calculation models among all electronic reliability standards, while keeping the required model parameters even simple to assess. With respect to ICs, SN is the only standard to distinguish between application types, for example operational amplifier, voltage supply, regulator, switched regulator, etc. In general however, SN is rather a simple standard with limited component type coverage and a limited set of different categories. Furthermore, it offers only one environment type, which is not even described at all.
